Gillian Forrester on gesturing gorillas, babbling babies and the origins of human language Oct 27, 2026

Show notes

What do the very first writhing movements of babies have in common with orangutans solving problems for food? Well, according to Gillian Forrester they may both offer clues about how we humans developed language.

Working with her great ape colleagues, Gilly Forrester – Professor of Comparative Cognition at the University of Sussex – has dedicated her career to finding out how we became the talkative, tool-using troop we are today.

Examining the link between movement, spoken language and social communication, Gilly’s research has looked at how brain organisation could affect the likelihood of being diagnosed with autism and ADHD, as well as how training dexterity may improve linguistic fluency in children.

In conversation with Professor Jim Al-Khalili, Gilly reveals what she believes it really means to be human, and the pair discover that despite his PhD in nuclear physics, Jim might not be quite as smart as a chimp.

David Canter on how psychology can save lives and catch killers Oct 20, 2026

Show notes

Although books and movies might suggest otherwise, catching criminals is of course less about hunches and gut instinct, and more about gruelling analysis of hard data - including when it comes to the psychological side.

David Canter is an Emeritus Professor of Psychology at the University of Liverpool, who took exactly this approach in the 1980s when he was asked to help police track down a serial killer. David had built his reputation as an environmental psychologist, studying how people behave in emergency situations and even advising the government on how to prevent disasters in football stadiums. But when he was asked to apply his unique methodology to help track down a serial killer and rapist, he realised that data-driven analysis of a suspect's behavioural patterns could be invaluable to any investigation.

David tells Jim Al-Khalili about how he founded the field of investigative psychology - and went on to advise on major criminal investigations, write award-winning books and even make time to pursue a parallel life as a composer.

Edith Heard on unravelling the mystery of X-chromosome inactivation Oct 13, 2026

Show notes

Imagine looking at a map of a city you thought you knew inside-out, only to discover a collection of tightly knit neighbourhoods that nobody had ever realised existed... Edith Heard has achieved something rather similar with DNA.

Edith is a leading expert in epigenetics: put simply, the science around how our bodies can turn particular genes on or off without actually altering our DNA. She’s spent her career studying the mechanisms that make us who we are and transforming our understanding of how X chromosomes are expressed; notably, how female cells turn off the spare X chromosome.

Talking to Professor Jim Al-Khalili, Edith discusses her journey from a shy and introverted youngster to the cutting edge of European science - including her latest role as Director of London’s prestigious Francis Crick Institute.

Ginger Kerrick on manning Nasa's Mission Control and getting to Mars Oct 06, 2026

Show notes

What do you do when your childhood dream of becoming an astronaut is grounded at the final hurdle?

If you’re physicist Ginger Kerrick, you go on to help run the missions instead.

After failing the medical of her astronaut application process, Ginger went on to become Nasa’s first non-astronaut CAPCOM and its first Hispanic female Flight Director. Across a remarkable three-decade career, she helped train the International Space Station’s first long-term crew, logged thousands of hours in Mission Control, and shaped future missions to the moon and Mars. All with her trademark determination and resilience – qualities forged through life experiences that might have derailed someone else entirely.

In conversation with Professor Jim Al-Khalili, Ginger reveals the highs and lows of life at Nasa, and discusses the future of human spaceflight: from the potential of AI, to missions to Mars.

Dean Lomax on discovering ichthyosaurs and defying nay-sayers May 26, 2026

Show notes

Have you ever been told you aren't good enough to do something, then gone ahead and proved the naysayers wrong by doing it anyway - in glorious, headline-grabbing style?

That is the satisfying story of Dr Dean Lomax. Dean grew up in Doncaster with a passion for fossils but after failing various school exams, was told by teachers that he'd never make it as a palaeontologist. Undeterred by leaving school with no qualifications, Dean sold his childhood Star Wars collection to fund a fossil-hunting trip to America that changed his life - after which a chance discovery led to him publishing his first ever scientific paper at the age of just 20.

Today, he’s an expert on ichthyosaurs - the massive marine reptiles that once inhabited our seas - and has discovered and named several new species, written books for both adults and children, and brought the prehistoric world to life on TV. Talking to Professor Jim Al-Khalili, Dean discusses dinosaurs as a 'gateway science', discovering the Rutland Sea Dragon and the importance of cutting out noise from nay-sayers to follow your dreams...

Helen Hastie on the future of human-robot relations May 19, 2026

Show notes

What if robots of the future weren’t just clever machines, performing tasks in isolation, but trusted teammates you could have a chat with? That could respond naturally to conversational cues and even explain their work?

Making this relationship a reality is a focus for Helen Hastie, Professor of Human-Robot Interaction and Head of the School of Informatics at the University of Edinburgh. Helen’s career has taken her from developing early dialogue systems - the ancestors of today’s generative AI - to working on sophisticated bots that can serve coffee with a side of small-talk, teach struggling kids with empathy, or provide calm and confident decisions as triage nurses. She’s also driven some of the UK’s flagship robotics initiatives, including as co-lead of the National Robotarium.

Talking to Professor Jim Al-Khalili - who reveals he was once told off for rudeness by an early chatbot - Helen explains her hopes for useful, reliable and ultimately trustworthy robots; machines that aren’t just in our world but a welcome part of it.

Seth Berkley on the importance of vaccinating the world May 12, 2026

Show notes

Dr Seth Berkley is an epidemiologist and global health leader whose career has been shaped by one central problem: vaccines save lives, but only if people can actually get them.

His 40-year career has spanned the global, from helping to build Uganda’s first HIV surveillance system and founding the International AIDS Vaccine Initiative; to leading Gavi, the Vaccine Alliance for more than a decade – overseeing the immunisation of hundreds of millions of children worldwide. And when COVID-19 struck, Seth co-founded COVAX, the global initiative designed to stop wealthy nations monopolising vaccines.

In conversation with Professor Jim Al-Khalili, Seth discusses the highs and lows of his globe-trotting career - from saving millions of young lives through vaccine distribution, to setting his own shattered leg after a climbing accident in Namibia - and addresses the huge challenge of tackling vaccine scepticism.

Presented by Jim Al-Khalili. Produced by Lucy Taylor. A BBC Studios production.

Hiranya Peiris on unravelling the story of the universe May 05, 2026

Show notes

Hiranya Peiris is playing a starring role in a movie that promises to tell perhaps the greatest story of all time. However, it’s a movie with a difference – there’s no director and no script. The Legacy Survey of Space and Time is one of the most ambitious projects in the world of astronomy, with a mission to create a decade-long time-lapse movie of the visible universe, to answer fundamental questions about its origin, evolution and, ultimately, its fate.

Hiranya is Professor of Astrophysics 1909, the prestigious Chair at the Institute of Astronomy at Cambridge University. Over her career she’s been one of the pioneers of a revolution in astronomy, bridging fundamental physics with the observational data coming back from space, to establish the first evidence-based standard model for the origin, evolution and fate of the universe. The endeavour has transformed the field from the ‘wild west’ of physics to the modern era of precision cosmology.

Ironically, it was another movie, of sorts, Carl Sagan’s documentary series ‘Cosmos’, that first sparked Hiranya’s interest in the universe as a young girl. Always keen to inspire women to follow in her footsteps and choose careers in science, if this interview were a live show she’d have reserved the front row for schoolgirls.

Washington Yotto Ochieng on the navigation tech that keeps our world moving Apr 28, 2026

Show notes

As a child growing up on the shores of Lake Victoria in western Kenya, Washington Yotto Ochieng once watched a plane cross the night sky and told his mother he wished he could travel on it. But he remembers her encouraging him to dream bigger...

Today, Washington is a Professor of Engineering at Imperial College London, and President of the Royal Institute of Navigation. Over a career bridging industry and academia, he has helped shape the movement of urban transport; how satellites guide us and locate us; and how governments manage the technologies underpinning so much of modern life.

Professor Jim Al-Khalili speaks to Washington about his inspirational upbringing, how reliant we've become on technologies such as GPS, and his work encouraging the next generation of engineers in both the UK and Africa.

Lucy Carpenter on how our oceans are destroying ozone Apr 21, 2026

Show notes

Working on a remote tropical island in the Atlantic might sound like some sort of romantic idyll - but trying to conduct scientific research on a windy, isolated volanic outcrop is no picnic, as Lucy Carpenter can attest!

Lucy is an atmopsheric chemist and a Professor at the University of York, whose work has helped to transform understanding of how oceans shape the air above them. She was one of the founding scientists behind the Cape Verde Atmospheric Observatory, established on São Vicente in 2006 and now a key global monitoring site. Measurements made there helped overturn a long-standing assumption: ozone loss is not solely a human-made problem. Lucy and her colleagues showed that gases released by natural marine processes can trigger chemical reactions that destroy ozone - demonstrating that the sea is not simply a passive backdrop to climate change but an active participant; affecting aerosols, clouds and ultimately the climate itself.

More recently Lucy's expertise has taken her into the policy arena, co-chairing the scientific assessment panel for the Montreal Protocol: the international agreement designed to protect the ozone layer.

In conversation with Professor Jim Al-Khalili, Lucy dicusses her journey from sampling ocean air to turning the tide of global environmental policy - and explains why her passion for duathlons could arguably be seen as an easier pastime than scientific research.
